Patented May 3, 1932 PATENT OFFICE RALPH L. LEE, OF DAYTON, OHIO,ASSIGNOR TO DELCO-LIGHT COMPANY, OF DAYTON, OHIO, A CORPORATION OFDELAWARE DOMESTIC APPLIANCE Original application filed March 31,1923,8eria1 No. 629,202. Divided and this application filed April 30,

1924. Serial The present invention relates to endless belt typeconveyors and particularly to conveyors for clothes wringers.

T he present application is a division of my copending application,Serial No. 629,202, filed March 31, 1923, which was issued January 22,1929, as Patent No. 1,699,599.

One of the objects of the present invention is to provide an endlessconveyor which can be readily uncoupled for the removal there-of.

Another object of the invention is to provide for minimizing thesquirting of water from the conveyor as it passes between the Wringerrolls. I

Anotherlobject of the invention is to provide for maintaining a conveyorbelt in alignment with the rollers with which the belt cooperates.

Further objects and advantages of the present invention will be apparentfrom the following description, reference being had to the accompanyingdrawings, wherein a pre ferred form of embodiment of the presentinvention is clearly shown.

In the drawings:

Fig. 1 is a fragmentary perspective view of a clothes wringer with myimproved clothes conveyor appliedthereto;

Fig. 2 is a plan view of a portion of the conveyor showing theconstruction of the conveyor and the method of lacing same; and Fig. 8is a fragmentary perspective view of the conveyor and lacing means.

9 Referring to the drawings, a clothes wringer is shown at 23 includingthe downwardly extending legs and 51 of the side frames of the wringer.1V ringer rolls 68 and 69 are rotatably mounted between the legs. Adrain board 58 is pivotally mounted to the legs of the wringer below therolls 68 and 69 in any suitable manner. The drain board includes sideframes 59 and 60.

Drainboard 58 is provided with a locking device for maintaining theboard in either This locking device comprises a sliding pin 63 carriedby the frame leg 50. Pin 63 has a notch 64- formed by flattening off aside of pin 63. A pin 65 inserted from the side of the frame leg 50 isreceived by the notch 64: and is adapted to cooperate with the ends ofthe notch to prevent the locking pin 63 from being pulled entirely outof the frame. Pin 63 cooperates with holes 66 and 67 in the side rail soas to lock the drainboard in either of its tilted positions.

The drainboard 58 provides a movable support for the movable wringerconveyor now to be described. At opposite end edges of the board 58. therails 59 and 60 carry rollers located parallel to rolls 68 and 69, oneof said rollers being shown at 96, it being understood that another isprovided on the opposite side of the wringer 23. Rollers 96 are adaptedto support a conveyor 97 interposed between the rolls 68 and 69 andtherefore rotated by the movement of these rolls. Roller 96 is ta peredand the like roller (not shown) on the opposite end edge of board 58 istapered so as to be larger in diameter at their centers than at the endsin order that, during the movement of the belt, the belt will remain inalignment with the wringer rolls.

To prevent gathering or crawling the conveyor belt 97 is preferably madeof two thicknesses of fabric, such as canvas. In making the belt, theends 97 a and 976 (shown folded back in the drawing merely for thepurpose of showing the lower layer of the canvas) are brought togetherat the center of the belt. A strip of tape 98 is sewed through the sideedges of the fabric to make a two-ply belt. Parallel stitchings 99 areprovided lengthwise on the belt to hold the plies together so that saidplies will together form a relatively stiff belt, so as to prevent thebelt from gathering.

A series of spaced loops 101 are sewed to the one end of the conveyorbelt 97 while spaced loops 102 are sewed to the other end of theconveyor belt. Loops 101 are adapted to fit within the spaces betweenthe loops 102 while the loops 102 ar ada 'ited to tit within the spacesbetween the loops 101. A 0 stave 108 is inserted into the loops 101 and102 to thereby lace the belt. Pairs of loops 104 shorter than loops 101and 102 are located at each side edge of the belt. One of these loops 10i is carried at each corner of it;

' of water will not be collected adjacentthe a 1 be trapped ano adjacentthe lacing in order the end of the belt fabric so as to engage the notchend of the stave 103.

These small loops 10 1 provide means for lacing the belt at the sideedges and prevent accidental removal of the stave. In lacing the beltthe stave 103 is first inserted through loops 101 and 102 as is shown inFig. 2. One of the notched ends is then inserted into the small'loops104 at one side of the belt97.v After one side of the belt is connectedthe other notched end 105 is inserted within the loo is riiiderstoodthat the belt will stretch sidewise so that'the loops 104 can bestretched over a notched end 105. Both ends of the conveyor belt arereinforced by tape 106 and 107 secured by stitching.

Means are provided for preventing a large quantity of water accumulatingbetween the plies at any one portion thereof, for example, to prevent arelatively large volume of water being squeezed out with considerableforce and squirtedupon the floor, workbench, or the like. This meanscomprises devices for trapping small quantities of water in pockets tobe progressively emptied so that the water will be squeezed outprogressively and in relatively small amounts. By avoidinganaccumulation of water, the water squeezed out in small quantities willrun down the con veyor belt onto the drainboard. To accomplish theseaims of the invention the belt. 97 is provided with transverseordiagonal stitchings 108. These stitchings cooperate with stitching 99 toform water dispersingpoclb ets. The belt 97 is generally water soakedduring the wringing operation and water tends to collect between theplies of the canvas. In order that a considerable quantity the slideedges.

104 on the other side of theb'elt. "It 7 The rolls therefore tend tograsp the belt more at the center than at the side edges, and,consequently, thebelt tends to track readily with the rolls.

It is to be understood that features of the present invention areadapted not only to clot-hes wringing apparatus but also to otherapparatus involving a rolling action in the mode of operation, such asmangles having one or more rollers adapted tobe driven by a powerdevice.

'While the form-of mechanism herein shown and described constitutes apreferred embodiment of one form of the invention, it isto be understoodthat other forms might be adopted and various changes and alterationsmade in the shape, size, and proportionof the elements therein withoutdeparting from the spirit and scope of the'invention.

What is claimed is as follows:

1. A wringer including a plurality of rollers. a conveyor belt having aplurality of plies and adapted for conveying articles between saidrollers, means associated withsaid'conveyor belt and cooperating withsaid rollers for progressively and gradually removing liquid frombetween the plies of said belt.

2. A wringer including a plurality of rollers, a conveyor belt having aplurality ofplies and adapted for conveying articles between up saidrollers, means associated with said conveyor belt and cooperating withsaid rollers for progressively and gradually removing liquid frombetween the plies of said belt, said means comprising stitchingextending transversely to the direction of movement-of the belt. i

lacing and there be squeezed out with considerable force, thediagonalstitchings 108 co operate with thelengthwise stitching 99 to form aseriesof pockets where the water will pushed in small quantities frombetween the plies of canvas. 1 When the belt 97 moves the water betweenthe plies of canvas will be trapped and then pushed out of pockets 109.\Nhen the conveyor belt 97 moves so that a portion indicated by the dotand dash line 110 moves under the roll the water between the plies ofcanvas between the diagonal stitches 108 will be trapped and then pushedout of a series of pockets 111.

In this manner small amounts of water are 7 pushed out from between theplies of canvas at aplurality of places with relatively little forceinstead of collecting at one place and being squeezed out withrelatively great force.
